All calls on-island are local calls; calls from one island to another via a land line are long distance and you must dial 1; then the Hawaii area code, 808; and then the phone number. Many convenience groceries and packaging services sell prepaid calling cards in denominations up to $50. Many public pay phones at airports now accept American Express, MasterCard, and Visa. Local calls made from most pay phones cost 50¢. Most long-distance and international calls can be dialed directly from any phone.

Calls to area codes 800, 888, 877, and 866 are toll-free. However, calls to area codes 700 and 900 (chat lines, bulletin boards, "dating" services, and so on) can be expensive -- charges of 95¢ to $3 or more per minute. Some numbers have minimum charges that can run $15 or more.

For reversed-charge or collect calls, and for person-to-person calls, dial the number 0 then the area code and number; an operator will come on the line, and you should specify whether you are calling collect, person-to-person, or both.
